Overview
Built for Glock pistols set up with slide-mounted red dot optics, this sight set is intended to provide a co-witness iron sight option and a dependable backup aiming reference. The XL height and tritium front and rear sights are paired with black outlines to support a clear sight picture, especially when used on MOS slides. It fits Glock pistol models excluding 42, 43, and 48, making it a focused choice for shooters who want optic-compatible irons rather than a general-purpose sight upgrade. The set is also available individually, which gives users some flexibility if they are matching an existing setup.

Considerations & Trade-offs
- Designed for slide-mounted red dot setups, so the taller sight picture may be more than you want on a pistol that will stay iron-sight only.
- Fits all Glock models except 42, 43, and 48, so compatibility needs to be checked before ordering.
- The set uses green tritium with black outlines front and rear; if you prefer a different color or outline style, this configuration is fixed.
- Ameriglo notes the product is not manufactured, authorized, endorsed, or warranted by GLOCK, so buyers should verify fit for their specific pistol and slide setup.
